Davico Catalytic Exhaust

About Davico Manufacturing

For over 35 years, Davico Manufacturing has been one of the automotive aftermarket's most trusted names in emissions and exhaust system components. Founded in 1988 and headquartered in New Bedford, Massachusetts, the company built its reputation by focusing exclusively on what it does best: engineering high-quality catalytic converters and exhaust parts that mechanics and do-it-yourselfers can rely on.

Davico's philosophy goes beyond simply making a replacement part — the company emphasizes understanding the root cause of exhaust and emissions failures so that repairs last. Their technical resources, training bulletins, and advisory materials reflect a commitment to education that sets them apart from typical parts suppliers. As Davico puts it, their goal is helping customers "keep the check engine light out and eliminate P0420 codes" for good.

Catalytic Converters: The Core of Davico's Lineup

The cornerstone of the Davico catalog is their extensive line of catalytic converters. With a catalog spanning over 4,000 product models covering passenger cars, pickup trucks, and vans from virtually every major manufacturer, Davico offers one of the broadest coverage ranges in the aftermarket industry. Their product range includes several distinct converter types to suit different needs:

• Direct Fit EPA Catalytic Converters — Bolt-on replacements installable with basic tools, designed to match OE specifications precisely.
• CARB-Compliant Catalytic Converters — Certified for use in California, New York, Maine, Colorado, and other states with strict air quality regulations, identifiable by Executive Order (EO) numbers embossed on the converter body.
• Dealer Alternative Direct Fit Converters — Purpose-built for high-mileage and poorly maintained vehicles where standard OE-spec converters may struggle to meet tight NOx and oxygen sensor switching requirements.
• OBD-II Universal Catalytic Converters — Flexible solutions for experienced installers who need to replace the converter body and substrate in custom or older applications.
• Split Y-Pipe Catalytic Converters — Designed for vehicles where the exhaust splits into dual channels, maintaining proper flow and emissions compliance.

A Complete Exhaust System Solution

While catalytic converters are Davico's specialty, the brand also manufactures a full range of exhaust system components to complement converter replacements. Their exhaust pipes are engineered as direct-fit replacements for damaged or rotted sections, eliminating the guesswork of universal fitment. Similarly, their exhaust tail pipes and exhaust resonator pipes round out a complete system offering, allowing shops to source all the components needed for a thorough exhaust repair from a single trusted manufacturer.

Davico also offers the SLEDGEHAMMER engine induction cleaning kit — a two-step fuel system treatment and rapid induction deposit cleaner. This product reflects Davico's philosophy that successful catalytic converter replacement depends on first addressing the underlying engine management and carbon buildup issues that cause converter failures in the first place.

Why Technicians and DIYers Trust Davico

Davico's products meet EPA and CARB standards, and many direct-fit units ship with new gaskets included to ensure proper sealing from day one. The brand's deep technical support — including training bulletins and advisory documents — makes them a go-to resource for repair professionals tackling emissions-related repairs. Whether you're a seasoned technician or a first-time DIYer, Davico's combination of broad coverage, engineering precision, and educational support makes them a brand worth knowing.
